Walmart(BEIJING) -- Walmart recalled its "Five Spice" donkey meat sold in Chinese stores after tests found the product contained meat from other animals.

Customers from stores in the city of Jinan will be compensated following the discovery of fox meat in the packaged snacks, according to the Los Angeles Times.

Supplier Dezhou Fujude Food Co. Ltd provided the donkey meat, which is a delicacy in some parts of China. The fox meat was discovered after DNA testing. Dezhou officials may have been placed under criminal detention, the Los Angeles Times reported, and Walmart is considering taking legal action.

"We have been deeply shocked by this incident," said Walmart China chief executive Greg Foran. "It has provided a deep lesson and shown that we need to continue to increase investment in supplier management."

Food safety issues aren't new for the Chinese government. In May 2013, reports surfaced that rat meat was being passed off as lamb, prompting arrests and investigations.
